MINING IMPLEMENT.

Specification of Letters Patent.

Patented Apr. 27, 1915.

Application filed January 14, 1914. Serial No. 812,111.

To all whom it may concern Be it known that I, ANDREW KoLnNIo, J r., a citizen of the United States, residing at Streator, in the county of La Salle and State of Illinois, have invented. new and useful Improvements in Mining Implements, of which the following is a specification.

The invention relates to a mining implement, and more particularly to the class of combined needles and scrapers for coal and other mining.

The primary object of the invention is the provision of an implement of this character which is extremely handy for use in mines whereby a hole can be bored and cleaned for the introduction of powder therein for exploding purposes.

Another object of the invention is the provision of an implement of this character which is extremely simple in construction, reliable and efficient in its purpose, and inexpensive in manufacture.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claim hereunto appended.

In the drawing :-Figure 1 is a perspective view of an implement constructed in accordance with the invention. Fig. 2 is a fragmentary vertical longitudinal sectional view thereof, with the handle removed. Fig. 3 is a side elevation of the handle detached.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the implement comprises an outwardly tapered body 5 having a pointed end 6, while its opposite end is flat as at 7 and to the latter of which is welded or otherwise fixed a diskshaped scraper blade 8 provided with a beveled scraping edge 9, the body, which is the needle proper, being of circular shape in cross section and contains openings 10 adapted to receive a rod or other device which enable the turning of the body 5 for its insertion or removal in or from powder which is confined within a hole bored by the use of a drill in the earth strata and set off by a squib in the ordinary well-known manner for exploding and breaking up the strata in the mine.

Mounted in the largerend of the body 5 and held fast therein in any suitable manner is an internally threaded sleeve 11, the outer open end of which detachably receives the threaded shank 12 of a handle 13 which is connected to the needle to enable the convenient handling thereof when in use, it being understood of course that the outer open end of the sleeve 11 extends through the blade 8 to be flush with the outer face thereof.

Swingingly connected to the outer face of the blade 8 by means of a pivot 14: is a cover plate 15 which is swung over the open end of the sleeve 11 to close the same and thereby exclude dirt or slack from entering the sleeve when the handle 13 is detached from the needle.

In the use of the implement the earth strata is bored or excavated to the desired or convenient depth, this being accomplished through the use of a drill as usual. After the bore has been made the said drill is withdrawn therefrom and the implement is now brought into use by inserting the disk 8 into the bore so as to clean or scrape it for the removal therefrom of the loose chippings or shavings of substance detached by the drill. A charge of blasting powder or other explosive material is then placed in the closed end portion of the bore, whereupon the implement is reversed in the hand of the user and its needle with its pointed end first is inserted in the bore or excavation and with its point reaching to or entering the charge of explosive. Tamping material is now introduced to the bore or excavation and rammed and pounded against the charge of explosive therein by means of any suitable tool. When the tamping material has been rammed or pounded sufficiently the needle is withdrawn and a train of fuse is laid in the priming hole formed by the needle, and ignited in due course, to the end that the explosive may effect its purpose.

From the foregoing it is thought that the construction and manner of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is The combination with a member having a recess in one end, an internally threaded socket member permanently fixed within the recess and having a portion extending beahle'engagement in the socket member'vvhen 1o yond the end of the member, a disk having the opening in the disk is exposed.
